UNITED STATES PATENT OFFICE.

NEW JERSEY, A'SSIGNOR T HYGTENIC TUBE COMPANY, OF NEWARK, NEW JERSEY,

A CORPORATION or NEW JERSEY;

GOLLAPSIBLE TUBE.

Application filed February 24, 1928. Serial No. 620,886.

To all whom it may concern: Be it known that I, HERMAN B. LERMnR, a citizen of the United States of America, residing at' Newark, in the county of Essexv and State of New Jersey, have invented new and useful Improvements in Collapsible Tubes, of which the following is a specification.

This invention relates to improvements in collapsible tubular containers, particularly such as are used for holding creams, pastes, emulsions, ointments, salves, etc., etc., in condition for use.

The main object of the invention is to provide a translucent or opaque tube having a screw-threaded dispensing nozzle provided with a removable cap at one end and a relatively rigid circular bottom at the other, the

tube being made of flexible material, prefer ably resilient so as to resume its'origmal I shape after being compressed.

Another. purpose is to produce a sanitary container, suited for liquids and. semi-liquid or plastic compositions, non-metallic, substantially unbreakable and unaffected by its contents for such contents being easily and instantly available upon deman A further aim is to produce a container tube that is light, strong, inexpensive to construct and of neat and pleasing'appearance.

These and like objects are accomplished by the novel design and construction or parts and illustrated in the forming an essenthis disclosure, and in which:- is a s de elevational view of a made in accordance with the tial part of Figure 1 collapsible tube invention.

Figure 2 is a longitudinal sectional view thereof. I

Figure 3 is a top plan view. Figure 4 is a bottom plan view. Figure 5 is an enlarged fragmentary sectional View showing its construction.

The main portion or body of the container consists of a seamless tube made of any of the well known pyroxylin or other nitrated cellulose compositions and in any preferred color, the wall being relatively thin and" translucent or opaque as may be desired.

At one endthe tube is contracted uniforml on all sides producing an inwardly curved shoulder 11 havin a neck 12 leading to an outwardly exten ing mouth or discharge element makes intimate contactan indefinite period of time,

nozzle 13 formed with coarse screw-threads,

thejedges ofthe neck being inturned to form a lip 14.

A cap 15 having an imperforate head 16 is provided with internal screw-threads to fit the neck and is formed with a knurled or corrugated band 17 for conveniently grip-' ping during removal or'replacement.

Within the cap is disposed a pliablewasher or gasket 18 adapted to rest upon the lip 14 and become firmly seated thereon when pressed by action of the cap.

The lower, opposi te endof the tubeis-cut squarely nular recess 19 formed in the bottom element 20 between the inner, downturned flanged wall 21 and the beaded outer element 22.

across and snug fitted intoan an-Q This bottomis made ,of similar material to the body, but relatively thick and ,so formed that the inner edge. of-the beaded v its full width witlr the cavity 24 in the bead maybe filled with a .suitable cement, as may also the inner corner 25 at the junction of the wall 21 and interior of the tube, as best shown in Figure '5.

The tube may be either assembled with the bottom and filled through the nozzle in the manner of a bottle, or the cap may be laced in operative position, holding the we er in place and the contents entered through the open bottom which is afterwards applied and cemented.

In operation, the cap-is removed and such portion of the contents exuded as may be required by compressing the wall of the tube with thefingers, and upon relaxing the pressure, the. wall. will return to it's normal original position, causing a suction that tends to draw in any portion of the contents that may adhere to the lip understood.

Due to the 'imperviousnature of the container, its lightness, strength, neamess and instant response to pressure or recovery therefrom, this device has been found highly satisfactory in service and results attained by its use.

From the foregoing it will be seen that a simple device for this purpose has been disclosed in the preferred form of its embodiand neck in a manner well body 10, while the annular memes cenfiicising Wich'the scope of the appende&

claim.

Having thus described my inventio'n; Whfi'ii 1' claim as new and. desire .iso secure by Let,-

te'rs Patent, is

' 11m e transiucen; container, a collapsible cube having a boiztom element, the tube and! iss befitcm element being made Wholly of ceiinlaid, said bottom element being more than twice the thickness of the Walls of the tube, a dowmfnumed flange lntegrel with saici bottam element, a raised cuter beaded memberf cm seie; flange farming an annular recess turned flanged HERMAN 1e.
